This paper addresses the influence of electric potential difference on the electroosmotic decontamination of two tropical soils from Brazil. The laboratory testing program encompassed: (i) two residual soils of gneiss, a C-horizon saprolite clayey silty sand (soil sample A) and a B-horizon sandy silty clay (soil sample B); (ii) mineralogical and chemica...
View ArticleA case study on the application of the parallel-seismic (PS) and induction-logging (IL) tests combined to evaluate the depth of a 25-cm diameter root-pile belonging to the foundations of a telecommunication tower located in Santana de ParnaÃba, São Paulo, Brazil, is presented. The foundation element is embedded ...
View ArticleCompacted earth embankments are routinely used in dams and many others infrastructure projects in Brazil. It is common to use fine-grained soils for these embankments, which are placed and compacted in the field at specific values of unit weight and water content. Their design is usually performed using geotechnical parameters from laboratory tests on c...
View ArticleThis paper presents results of field and laboratory permeability tests aimed at evaluating the performance of mineral barriers for the containment of organic liquids (Non Aqueous Phase Liquids, NAPL). Experimental landfills were constructed following optimal ranges of variation of soil index properties proposed previously and the performance of the land...
